JENETTA V. BOHANNAN, OF WASHINGTON, DISTRICT OF COLUMBIA.

CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 456,644, dated July 28, 1891.

Application filed July 10,1890. Serial No. 353.250. (No model.)

To cir/ZZ whom it may concern:

Be it known that I, J ENETTA V. BOHANNAN, a citizen ot the United States, residing at XVashington, in theDistrict of Columbia, have invented certain new and useful Improvements in Cigarette-Machines; and I do hereb declare the following to be a full, clear, an exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for making cigarettes; and its object is to feed into the machine the tobacco which is the filling of the cigarettes, the paper which is their covering or outside, and the paste which unites the same, and to perform the various oliices necessary to forni cigarettes of these materials automatically.

To this end my Ainvention consists in the construction and combination of parts forniiug a cigarette-machine hereinafter described and claimed, reference beingv had to the accompanying drawings, in which- Figure l is a longitudinal vertical section of a cigarette-machine according to my invention, taken on the irregular line l of Fig. 2, which is a plan view thereof. Fig. 3 is a transverse vertical section on line 3 of Fig. l, and Fig. 4 is a cross-section ot' the feedingbox at line 4. Figs. 5, G, 7, and S are transverse vertical sections through the truck appurtenances at the lines, respectively, 5, 6, 7, and 8 of Fig. 2; and Fig. f) shows the shearingot't` blades, both as seen at the top edge and at their inner or rear face. Fig. l() is a detail View ot the delivery end of the feedingbox. `Fig. ll is an enlarged detail view of trough d in cross-section.

c represents the body or frame ot the machine.

b is a roll of paper of the proper width to wrap around a cigarette and have its edges overlap enough to be firmly united by paste. This roll is journaled upon brackets c, fixed to the rear end of the traine, and the paper is drawn therefrom through a stationary trough d, having inward-.projecting lips e, under which the edges of the paper are guided.

j' is the tobacco-feeding box, ot' a width to receive a wide plug or layer oi' tobacco and only deep enough to admit the thickness of one plug.

g g represent screws located in grooves longitudinally in the bottom of the feed-box, the height of the screw-thread projecting above the inner face of the said bottom. The lid z of this box is in two sections h 1l, hinged at one edge to the box and provided with hooks l7' at the other edge, whereby they may be pressed down upon the tobacco to hold it in engagement with the threads of the screws g.

' The delivery end of the box is provided with a fixed sheanblade 7e, over which the tobacco is continually fed by the screws g, which are kept in motion by the beveled gears Z, sprocket-wheel 1u, chain n, and the sprocket-wheel o, which is on the machine-shaft p.

q represents a series of blades or cutters rigidly secured on the two cutter-heads r, which are iixcd upon a shaft s, that is journaled in bearings in posts fixedto the frame a.

u represents a pulley on shaft s, whereby power may be received to run the machine, and `n represents sprocket-wheels and fn a chain communicating motion from the cuttershaft .9 to the machine-shaft p. The blades q in revolving come in shearing contact with the fixed blade 7U', thus shearing oit the to baeco in fine long shavings as fast as it is fed in by the screws g. The shavings fall from the inner faces of the blades within the cyl inder as they revolve, and I provide a heavy curtain l0, hung by bearings ll freely upon the shaft s, and a wiper 12hinged to the lower edge of the curtain to wipe the tobacco shavings from each passing blade and permit the shavings to drop between the blades into a hopper 13, which guides them int-o the covering-paper in the trough d. The curtain l0 prevents the shavings from being thrown around by the blades, and the wiper l2, being hinged to the lower edge of the curtain and weighted on its back, is enabled to drag upon the backs of the blades and wipe the shavings of tobacco oit to fall between them. The

wiper, when at its lower limit, does not quiteA reach the sharp edge 01": each blade, but strikes a little back of it, and a spring may be added to quicken the fall of the wiper, if found necessary. The lid 7L is in two sections 71. and t', in order that tobacco may be supplied without stopping the machine by permitting the section 7L to remain closed upon the remaining tobacco, while the section i is raised to add the new supply, and pains should be taken to crowd it firmly against that already in, so that there be no interval in which the blades are not supplied.

14 is a metallic jaw rigidly fixed at the delivery end of the lid-section h to enable it and the blade le to hold the last ends of plugs, as in a vise, While being sheared off. The action of the screws g is so strong and positive that they will forward the tobacco against great resistance of the pressing lid-sections t 'L'.

15 is a wheel having a half round groove in its edge and of a width to enter the paper wrapper while held in U shape and compress the tobacco shavings therein to the size and form suitable for cigarettes while the same is continuously drawn along beneath the said wheel. The wheel is kept revolving at the same speed that the paper and filling advance by means of pulleys and belt 16, which receive motion through a cross-shaft 17 and beveled gears 18 from the machine-shaft p.

19 is a roller for supporting the paper b in line to enter the trough d when the roll of paper becomes reduced in size.

20 21 represent the closing jaws gibbed to slide transversely in truck 22, which are connected together in a continuous chain by means of hinges 23.

24 represents a pair of pulleys jou-rualed in the frame upon shafts connected by beveled gears 18 and 25 with the machine-shaft p and kept continually rotating thereby. These pulleys are many-sided. I here show them with four sides, each side corresponding to the length of a truck, and the continuous chain of trucks is rotated by the pulleys.

2G 27 represent the j aw-closers rigidly fixed to the frame in the path of the outer edges of the jaws, and they have flaring inner edges at their rear ends 28 to guide the advancing jaws inward. These trucks are all provided with half-round troughs 29 to register with each other in line with the trough d to receive the filled wrapper after it passes the compressing-wheel 15. The jaw 2O has a sharp-edged lip 30, beneath which is a quarterround groove to register when closed with the trough 29, and the jaw 2l has an overhanging lip 31, fitted to pass over and register with the lip 30 in loose contact, and beneath the lip 31 is also a quarter-round groove registering when closed with the trough 29, the two jaws and the said trough completing the circle or cylinder to surround and compress the wrapper and filling into circular or cigarette form. (See Fig. G.) The closer 27 stands a little forward of the closer 26, so that thejaws 2O in advancing meet the closer 26 before the jaws 2l meet their closer 27, and each jaw 20, advancing its lip 30, closes one edge of the Wrapper upon the filling. Then immediately afterward each jaw 2l advances its lip 31 and closes the remaining edge of the wrapper over the lip 30, as shown in Fig. G.

32 represents a paste-reservoir, preferably niade with liexible sides like a bellows, supported upon the frame by a post 33 and ring 34. The lower end of the reservoiris piston like, provided with a rack toothed piston r0d 35, which communicates with the machineshaftp by suitable gearing to continually press the piston up, so as to force out the paste from a nzzle' 3G as fast as required.

37 is a stop-cock 0r throttle-valve in the pipe connecting the nozzle with the reservoir, whereby the rate of delivery of the paste may be governed. y The nozzle 3G, Fig. 7, is fixed in line of the closed lips 30.Fig. 6, sothatthe closed edges of the paper wrapper rub it above and below in passing, and the nozzle is provided with a suitable outlet and spreader at its lower side to deliver and spread the paste.

38 is a closing-ring supported on an arm fixed to the frame and located in the line ot the trough 29, and the filled and pasted wrapper is drawn through this ring, whereby the pasted edges are closed and firmly pressed together, and the whole is thus rounded into the form of a continuous cigarette.

39 represents a second chain of grooved trucks similar in their connections, mounting, and movement to the trucks 22.

40 represents square pulleys, which carry the trucks 39, similarly geared to the machineshaft p to run at the same speed as the trucks 22. The office of these trucks is to pull the `continuous cigarette forward over the pasting-nozzle and through the closing-ring and to cutoff the rod into lengths for single cigarettes by means of gripping-jaws 41 42, gibbed to slide transversely upon the trucks 39. Each jaw is provided with a quarter-round groove to register when closed with the trough in the truck, forming therewith a cylinder of a size to grip the cigarette rod. The jaw 41 is provided with a sharp-corner-edged shearblade 43, having a half-round notch 44 to receive and support one side of the continuous cigarette, while a sharp-edged blade 45, projecting from the opposite jaw 42, is driven past it in shearing Contact, as shown in Fig. 9, to cut off the cigarette.

4G and 47 are closers, respectively, for the jaws 41 and 42, and the closer 47 is farther in advance than the closer 4G, so that the jaw 41, with its blade 43, is closed against one side ot' the continuous cigarette before the jaw 42 begins to close, in order that the 'continuous cigarette may be firmly supported when the blade 45 enters it. The blades are at the forward ends of the trucks,vin order that the jaws may continue to pull forward lthat portion of the continuous cigarette in their rear after the cutting, and the closers keep the two jaws ahead of the cut firmly closed to support the cigarette while being cut off, thus insuring a square cut. Then the jaws 2O 2l pass their closers, they are suddenly forced open by springs 48, leaving the continuous cigarette to be pulled along by the jaws 41 42, and when the latter pass their closers they are sprung open by similar springs, (not IOO IIO

showm) delivering` the completed cigarettes 59 in rapid succession. The trucks 39 are provided witli rigidly-fixed slices tft, each shoe having` two knobs or rollei's 50 adapted to slide or roll on the side rails 5l, which are fixed to the frame ci in planes above and below the pulleys 40, the ends of the rails being rounded to even the path of the trucks, and each truck has the two knobs or rollers 50, one at each end, in order that its ends may not be raised above the path of the proper travel when the middle passes over the curve 52, as it would be' raised if there were a straight line of bearing along the middle as well as at the ends. The trucks 22 are similarly mounted to slide on rails by means of shoes 54, having end knob-bearings 55. The sliavings of tobacco by falling continually from the rotary blades into the wrapper overlap in length, so that the continuous cigarette is equally strong at all points before it is cut into cigarette lengths.
